Newsletter to Repository in Wordpress (Easy Way, Fast and Possible to Automate?)

Hi there, I'm sending my newsletters with FluentCRM, and now I want to create an online repository of these ones as fast as possible.

I will like to know if it is possible to export the final version easily to HTML even I created originally with the visual editor, to be able to copy the HTML and create an entry on Wordpress to be able to post every newsletter easy and fast?

Is anyone doing this? Is kind of what Beehive does and I'm looking to replicate this in my Wordpress and trying to automate if possible or doit as fast as possible.

Looking to hear from your experience and ideas, thanks!
